AWKWARD ZOMBIE

So I have to give you one-sided arguments against it?
Fiiiine.
It's illegal (file-sharing itself is not, only if it's copyrighted material obvs.)
You should buy it to give the artist cheddar if you like the artist that much.
aaand that's it pretty much.

It encourages the use of programs and counter measures that harm the freedom of the legal consumer, and make it difficult to use the content when purchased legally.

I can probably help with any basic questions regarding printing, should they ever arise.

TOO BAD FOR YOUR I'LL NEVER BE ON TO HELP YOU AHAHAHAHAHAHAHAHA

Sooo.... Hexadecimal.

Letters add and become numbers
While Numbers add into letters?

I am glad I don't have a class with this, but its best to be prepared

Hey there. Computer guy reporting in.
Hexadecimal system is a system with 16 numerals, instead of our 10.
because there's only numerals from 0-9 they use A for 10, B for 11, C for 12, D for 13, E for 14, F for 15.

A hexadecimal number is built like follows:

Example:
AF2219

9 times 16^0 +
1 time 16^1 +
2 times 16^2 +
2 times 16^3 +
F=15 times 16^4 +
A=10 times 16^5
= way too much I should have taken a smaller number it's 11,477,529 I think.

for longer numbers keep counting up.

To calculate a hexadecimal number from a decimal number... I'd recommend calculating the binary of the number first (I explained that in an earlier post) then from the right taking groups of 4 bit each and calculating back to decimal, then the hexadecimal of that. Since it's 4 bit it's exactly from 0 to 15.

Example:
decimal: 25
to binary:
25/2 = 1
12/2= 0
6/2= 0
3/2= 1
1/2= 1
= 11001

-> (000)1 1001
-> 1 and 9
-> 19 is your hexadezimal of that number

Is it required by many professors such that binary must be in sets of eight?

Depends on what you want to do with them.

If a sequence is set up as 00010011,
would it be better to use 00010011 or 10011?

Depends on what you want to do with it. If you want to do calculations it's good to have a set length for example. If you just have the number as it is there's nothing wrong in dropping the 0s at the beginning. You're not writing 00000007 eitherwhen you want to write 7.

True, but I am very unfamiliar with binary.

No. does it have to do with binary?

Yes here's a link:

Is this the new "IT for dummies"?

It's really humo(u)rous, while educational

Think animaniacs and schoolbooks

EDIT: the new way things work has binary and computer stuffs

It also talks about everything from simple and complex machines to nuclear fission and fusion.

Making the switch to any numeral system is easy once you realise how numeral systems work. It's often easiest to read the numbers from right to left, the symbols you read (0-9 for decimal and below) are multiplied with the numerals base to the lowest power (0) and each position you move to the left increase the bases power by 1. If you add all that together you get the amount in the decimal system. eg (example numbers are random)
decimal (base 10): 5789=5*10^3+7*10^2+8*10^1+9*10^0
binary (base 2): 1101011001=1*2^9+1*2^8+0*2^7+1*2^6+0*2^5+1*2^4+1*2^3+0*2^2+0*2^1+1*2^0
For hexadecimal, we don't have enough symbols with the decimal ones so we'll just take some from the alphabet like D-vid said:
hexadecimal (base 16): AF14=10*16^3+15*16^2+1*16^1+4*16^0
For decimal points, just subtract from 0 the farther to the right you go from the decimal point (as far as I know it's never used in binary or hexadecimal): 0.63=0*10^0+6*10^-1+3*10^-2

It's pretty straightforward, I'll show you how to easily convert decimal to other bases when I've got some sleep. As far as notation goes, your professor will tell you what he prefers, mathematically it doesn't matter but computer related stuff will probably prefer the 8-bit notation for decimal.

I dunno why I did this since D-vid explained it very well... I blame procrastination.
